In the Immortal world, cultivation could replace sleep. The original body only slept four hours a day in the book. In order to survive, Dong Xi had to work harder. At most, she would not sleep and could train for four more hours a day. At that time, her cultivation would definitely be higher.
When she reached the third level of Qi Refinement stage, she could accept missions from the sect and go out to train. If she encountered some fortuitous encounter, she might be able to Reach Foundation Establishment. Thinking of this, Dong Xi sat cross-legged, closed her eyes, and began cultivating.
Dong Xi cultivated until the sun had set and her stomach started growling. Only then did Dong Xi realize that it was already very late and it was time to eat. Dong Xi walked to the entrance of the canteen and realized that it had long since closed. She touched her rumbling stomach.
